Abstract Background Routine colonoscopy is recommended to determine the coexistence of colon cancer after medical treatment for colon diverticulitis. However, in the case of uncomplicated diverticulitis diagnosed by computed tomography, the clinical relevance of routine follow-up colonoscopy has recently been debated. Yet, the role of follow-up colonoscopy for right colon diverticulitis, which tends to develop at a younger age than left colon diverticulitis, has not been specifically evaluated. Therefore, we aimed to evaluate the incidence of right colon cancer or colonic adenomatous polyps, detected by routine colonoscopy, after conservative management of acute uncomplicated right colon diverticulitis. Methods Patients with uncomplicated right colon diverticulitis (modified Hinchey stage Ia) diagnosed by computed tomography imaging, between 2011 and 2017, and who underwent follow-up colonoscopy surveillance after treatment were included. The primary outcome was the incidence of colon cancer, with the detection rate of adenoma being the secondary outcome. Information for analysis was retrieved retrospectively from patients’ medical records. Results The study group included 330 consecutive patients, with a mean age of 41.9 years, and 51.9% being men. For the primary outcome, the rate of colon cancer on follow-up colonoscopy was 0.3% (1/330 cases). The rate of adenoma detection was 20.9% (69/330 cases) and advanced adenoma (> 10 mm in diameter; or exhibiting a > 25% villous component or severe dysplasia), including colon cancer, was observed in 9 patients (2.7%). Conclusions In patients with acute uncomplicated right colonic diverticulitis, routine colonoscopy after conservative treatment may be necessary because although the colon cancer detection rate is low, it is possible to detect advanced colon adenoma.

Background Pericolic fat stranding on computed tomography (CT) scans has been an important feature for staging colon cancer. However, the factors associated with pericolic fat stranding have not been elucidated to date. Purpose To determine factors associated with pericolic fat stranding of colon cancer on CT colonography (CTC). Material and Methods Overall, 150 patients with 155 colon cancer lesions were retrospectively assessed by two radiologists for pericolic fat stranding on CTC. Circumferential proportion of the tumor (CPtumor; <50%, 50–75%, and ≥75%), longitudinal length, depth of invasion (≤T2, T3, T4), lymph node and distant metastasis, and lymphovascular invasion were recorded. Univariate and multivariate logistic regression analyses were performed between pericolic fat stranding and each factor. Multi-group comparisons were performed for the CPtumor and depth of invasion. Results Pericolic fat stranding was identified in 57 lesions (36.8%). Univariate analysis revealed significant associations of pericolic fat stranding with all factors ( P < 0.027), except for lymph node metastasis ( P = 0.087). Multi-group comparisons revealed that pericolic fat stranding was more frequent with increasing CPtumor ( P < 0.001); however, no significant differences were observed beyond subserosal infiltration ( P = 0.225). Logistic regression analysis revealed the CPtumor (<75% vs. ≥75%; P = 0.008, <50% vs. 50–75%; P = 0.047) and longitudinal length ( P = 0.001) as explainable variables. Conclusion Pericolic fat stranding identified on CT images of colon cancer is demonstrated more frequently with increasing circumferential proportion of the tumor and longitudinal length.

This study describes the efficacy of the evaluation of blood vessel anatomy by 3-dimensional computed tomography (3D-CT) for laparoscopic surgery for transverse colon cancer (TCC). A total of 102 patients with TCC were examined by preoperative 3D-CT to clarify their blood vessel anatomy at Tokyo Medical University Hospital between January 2010 and December 2015, before undergoing laparoscopic surgery using the obtained 3D-CT data. Regarding blood vessel variation, the middle colic artery (MCA) was present in all patients (100%). The common duct type was observed in 89 patients (87.3%), and a type of branch separate from the superior mesenteric artery was observed in 13 patients (12.7%). The accessory MCA was present in 25 patients (24.5%). The middle colic vein was present in all patients (100%), and it drained into the following vessels: the superior mesenteric vein, gastrocolic trunk, first jejunal vein, and inferior mesenteric vein [67 (65.8%), 25 (24.5%) 8 (7.8%), and 2 (1.9%) patients, respectively]. Regarding the surgical outcome, the bleeding volume was 43 g, the operative time was 218 minutes, the number of harvested lymph nodes was 21, the proximal resection margin was 164 mm, the distal resection margin was 105 mm, and the length of postoperative hospital stay was 10 days. Although complicated variations and anomalies in the MCA and the contiguous veins were observed, preoperative 3D-CT will be useful for surgeons performing laparoscopic surgery on patients with TCC.
